Cast Planar Incision by paying its mana cost, blinking Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Archaeomancer and all other cards that were exiled with it to the battlefield.
Abdel Adrian and Archaeomancer trigger.
Resolve the Archaeomancer trigger, returning Planar Incision from your graveyard to your hand.
Holding priority, activate any number of nonland permanents you control by tapping them, adding at least enough mana to cast Planar Incision.
Resolve the Abdel Adrian trigger, exiling Archaeomancer and the mana-producing permanents until Abdel Adrian leaves the battlefield, and creating a 1/1 Soldier creature token for each permanent exiled this way.
Repeat.
This ingenious loop turns Abdel Adrian, Gorion's Ward into an engine of endless cyclical reincarnation, fueled by the recursive magic of Archaeomancer. By kicking things off with Planar Incision, you blink Abdel so that he can repeatedly swallow and regurgitate your board, generating an army of Soldier tokens alongside infinite entry and departure triggers. Every single cycle, Archaeomancer dives into your graveyard to fish back the very spell that started it all, ensuring the sequence never runs out of steam.
